There are several aspects that go into having a successful day in the Vineyards:
Group Size has a major factor on what sort of day you should be planning for
2-7 people - With this size group you can run your day as you please as long as you are happy just to taste at the public bar within wineries. Most wineries require groups of 8 or more to book but smaller groups are welcome to just drop in spend as long or as little time with them before moving onto next venue.
8-20 people - Bookings are a MUST HAVE, with this size group you will have to allow 1-hour minimum at each winery & 1.5 to 2 hours for lunch
20 & above - Bookings are a MUST HAVE, with this size group 1.5hrs at each winery is recommended & 1.5 to 2 hours for lunch.
